The company also revealed some new milestones: a year ago, 10 percent of unique users visiting LinkedIn were using at least one of its mobile apps, while today the number is over 23 percent. Furthermore, LinkedIn insists it’s now easier to sign-up for the service directly from your mobile device, which now accounts for 15 percent of new member sign-ups. Not bad at all.

So, what’s new in the apps? Well, this slideshow pretty much sums it up:

While the above 16-slide presentation doesn’t mention Android, and the app hasn’t been updated at the time of writing, LinkedIn says that everything new for iPhone applies to Android. That means real-time notifications (when someone likes what you’ve shared, views your profile, accepts your invitation, and so on) as well as mobile company pages (they show of your connections work at the company, as well as recent news and updates, and current job openings). Oh, and LinkedIn has added access to job listings and jobs you may be interested in, directly into your mobile update stream.

The iPad of course gets its own treatment, but it’s nothing huge. In addition to the new notifications and updated company pages, Apple’s tablet now supports six new languages: French, German, Italian, Spanish, Brazilian Portuguese, and Korean.

There’s one more thing. LinkedIn has promised a new feature: “We’ve also heard from many of you that you’d like the ability to edit your profile from our mobile apps. Happy to let you know this is coming soon.” Unfortunately there’s no date, but we’ll be the first to let you know when it’s live.
